Hi David,
Ref: <http://www.w3.org/WAI/ER/conformance/ED-methodology-20120904#step1d>
During the WCAG WG you spotted a paragraph that could be misread:
[[
This definition of target users and tools must meet the terms defined in
WCAG 2.0 Level of Assistive Technology Support Needed for "Accessibility
Support" and must be used throughout the evaluation. For example, it is
not possible to evaluate some pages with one set of tools and other
pages with another set. Accessibility support must be uniform throughout
a single website.
]]
AFAIK the intent was not that the evaluator needs to test with the same
set of tools but rather that there is consistent support for a minimum
set of browsers and assistive technologies across the website.
How about this suggestion to replace the paragraph above:
[[
This definition of target users and tools needs to meet the terms
defined in WCAG 2.0 Level of Assistive Technology Support Needed for
"Accessibility Support" and needs to be supported throughout the
website. For example, if one part of a website is accessible using one
set of tools that is different from a set of tools is needed to access
another part of the same website then the website is effectively not
accessible for some users. Accessibility support needs to be uniform
throughout a single website.
]]
Does that address your concern?
Regards,
Shadi
